Summary

New discoveries for hearing loss intervention are often impeded by the proprietary nature of commercial hearing aids and their use in scientific research as "black boxes". An open-source speech platform (OSP) was developed to bridge the gap between audiology research and commercial hearing aid features, to promote innovative solutions to meet the needs of the hearing loss community. The OSP can replicate functions found in commercial hearing aids, and provides tools to researchers to access those functions. The purpose of this study is to evaluate portable and cloud-based platforms of the OSP that will enable a wide range of lab and field applications. All human subjects-related activities will be conducted at Northwestern University (single-site study).

Conditions

Interventions

DEVICE

Portable OSP

The portable open-source speech processing platform (OSP) is accessed on a browser via a wireless fidelity (WiFi)-enabled portable communication device that carries out all the signal processing. The processed sounds are transmitted to the ears via earpieces known as behind-the-ear receivers in the canal (same as those available with commercial hearing aids). The amount of amplification with the portable OSP will be customized for each listener based on a validated prescription.

DEVICE

Cloud-based OSP

The cloud-based open-source speech processing platform (OSP) is hosted on a web-server which includes the software for all the signal processing. The processed sounds are transmitted to the ears via calibrated headphones. The amount of amplification with the cloud-based OSP will be customized for each listener based on a validated prescription.
